One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

The USDA zone info for Audubon can be reviewed to estimate when to plant sutera.

Planting Calendar for Sutera

Frost tolerance for sutera:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since sutera are one of those plants that can tolerate a tiny bit of cold weather you can plant them just a tiny bit earlier in the year than more sensitive plants.

The earliest that you can plant sutera in Audubon is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant sutera and expect a good harvest is probably August. If you wait any later than that and your sutera may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your sutera indoors.

Last Frost Date

The average date of last frost is April 15 in Audubon. You should expect an average low temperature of 0°F in the coldest months of winter.

Since the USDA zone info for Audubon may not be accurate from year to year the actual date of last frost can change quite a bit from year to year. Since half of the time in Audubon you get a frost after April 15 be ready to cover your sutera in the event of one of those late frosts.
